HATTIE CHEESMAN LA MAR, OF HARRISON, OHIO.

. FOUNTAIN TOOTH-BRUSH.

To (/77 whom it may concern:

lie it known that I, HA'r'rm CHEESMAN L.-\ MAR, a citizen of the UnitedStates of America, and resident of Harrison, R. R. No. 2, in the countyof Hamilton and State of Ohio, post-office address Harrison, R. R. No.2. in the county of Hamilton and State of Ohio, have invented certainnew and useful Improvements in Fountain Tooth- Brushes; and I do herebydeclare the following to be a full and exact description thereof,reference being had to the accompanying drawings, making part. ofthisspecification.

This invention is a fountain brush, and relates more particularly totooth brushes, having for its object to store water or a liquiddentifrice on the brush and to control the supply of the same to abrushing element for the purpose of cleaning the teeth.

The invention consists of a handle provided with a head having a pocketformed therein said pocket being provided with apertures leading to thebrushing element, a reservoir mounted on the handle, said reservoirhaving gradually reduced walls, and a discharging chamber provided witha plurality of nozzles integral therewith, said discharging chamber ofthe reservoir being positioned within the head of the brush for thepurpose of discharging liquid from the reservoir to the brushingelement, and means for charging the reservoir.

The invention consists further in the features of construction andcombinations of parts hereinafter described and specified in theappended claim.

In the accompanying drawings illustrating the preferred embodiment ofthe in vcntion: Figure 1 is a side elevation of a brush embodying theimprovements. Fig. 2 is a longitudinal sectional view on the line 2.2ofFig. 3. Fig. 3 is a top plan view of the brush, and Fig. :i is a bottomplan view thereof.

The handle A may be of any desired or preferred material, and isprovided with a head F and with the usual brushing ele ment, such asbristles E secured to the lower face thereof. The head F of the brush ispreferably composed of the lower wall e, which is shown as an extensionof the handle A, and the upper wall f substantially parallel with thewall 6, said walls 6, f, being connected at (Z thereby forming a pocketl) \\'ithin the head, as shown in Fig.

2, the parted, a, f, forming the head, being shown as an extension ofthe handle. The lower wall a of the head is provided with a plurality ofapertures g establishing com-- munication between the pocket D and thebristles E. The diameter of the head is preferably reduced where itjoins the, handle A, as illustrated at h in Figs. 3 and 4. where thehead isprovidcd with supporting arms 2'.

A reservoir B, of any desired collapsible material, such as rubber, issuitably mounted on the handle A, said reservoir being shown of greatestdiameter at Z) with its top and side walls gradually converging towardthe head of the brush to a point at k of the brush where the reservoiris of least diameter; then said reservoir is extended to produce adischarging chamber B which is preferably of a contour to fit within thepocket D of the head F of the brush. This discharging chamber 13 isprovided with a plurality of nozzles 13 which are adapted to projectthrough the apertures g in the head, and communicate with the bristlesE. The reservoir B is provided, also, with a charging port bt adapted toregister with a threaded aperture 11 in the handle A, said charging portbeing closed by suitable means, such as a threaded cap 0. The reservoirB may be secured to the handle A by any suitable means. For example, theupper surface of the handle, as well as the walls of the pocket D, maybe coated with a water proof cement, and, if desired, that portion ofthe bulb B, and itsextension, which engage the portions of the handleand the head, may also be coated with the cement. The' extended portionof the reservoir B (forming the discharging chamber) is then insertedinto the pocket D of the head, using a suitable tool passed. throughaperture b if necessary. The nozzles B being of the same flexiblematerial as the reservoir, may be readily passed into the pocket of thehead until they come into alinement with their respective apertures g ofthe head. A suitable tool is now passed through the apertures g of thehead and into engagement with the nozzles B for the purpose of drawingsaid flexible nozzles through the aperturesg. The nozzles will then bedrawn to the position substantially as illustrated in Fig. 2, in orderthat the material contained in the reservoir may be;

discharged substantially near thebase of the brushing element. When theportion B and nozzles B have been placed in their proper positions, thereservoir may be inflated and the cement allowed to dry, retaining theparts in their normal operative p0- sition. v

The handle A is preferably tapered to conform to the generalconfiguration of the reservoir, as shown, thereby so positioning thegreatest diameter of the reservoir that it will be convenient tocompress the same when the brush is grasped in its rnormal workingposition.

lhe reduced portion of the reservoir, forming. the discharging chamberfitting within the pocket of the head, serves to re tain the parts incooperative position, while the reduced or converging portion of thehead it operates also to retain the discharging chamber of the reservoirwithin the pocket. 7

in operation, liquid such as water or a liquiddentifrice, is admittedthrough the charging port 6 to the reservoir B, the cap C being thenplaced in position. By compressing the walls of the reservoir, theliquid contained therein will be forced from the discharging chamber Bout through the noeaaae nozzles l3 and between the bristles E. It isobvious that liquid will not ordinarily flow from the reservoir to thebristles except when discharged from the reservoir by the compression ofits walls.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is As a new article of manufacture, afountain tooth brush consisting'essentially of a handle provided with ahead having a pocket formed therein substantially as shown anddescribed, a collapsible reservoir mounted upon said handle and providedwith discharging chamber, said discharging chamber being fitted withinthe pocket of said head, a plurality of nozzles integral with thedischarging chamber and communicating with a brushing element, the topand side walls of said reservoir gradually converging to a point nearthe head of said brush, and means for charging said reservoir.
